Among the mid-season varieties suitable for long-term storage and being universal in use, one can distinguish the NIIOH 336 carrot variety, bred by Russian breeders in 1978.

The high yield and keeping quality of the variety allow, subject to the rules of agricultural technology generally accepted for carrots, to get a good harvest with the possibility of long-term storage.

Due to the increased content of carotene and a number of other advantages, NIIOH 336 carrots have firmly won the love of gardeners throughout Russia.

What is the difference from other species?

This variety is distinguished by:

  • increased carotene content (23%);
  • the possibility of using for baby and dietary food.

Advantages and disadvantages

The advantages of the variety include:

  1. high productivity;
  2. good keeping quality;
  3. adaptability to growing in almost all regions of Russia;
  4. versatility in application;
  5. increased carotene content (up to 23%).

The main disadvantage of this variety is its average immunity to most carrot diseases.

Detailed characteristics and description of the variety

  • Appearance (shape and color of the root crop). Carrots grows cylindrical with a blunt end, weighing from 90 to 110 g. In length, carrots reach 20 cm, diameter - up to 4-5 cm. The surface, pulp and core of the root vegetable are intense orange in color.
  • Sowing time. For the NIIOH 336 variety, the average planting time is applicable - late spring, when stable warm weather has already established and when the danger of return frosts has passed.

    In the Middle Lane, this time falls in the third decade of April, in Siberia - planting begins no earlier than May. In the southern region, traditionally, sowing dates begin earlier than anyone else - in the first and second ten days of March.

    But this variety can be planted before winter, in late October - early November, when the air temperature has not yet dropped below 5 ° C.

  • What is the yield from 1 hectare. The variety belongs to the productive one - from 1 hectare you can harvest from 28 to 54 tons of carrots.
  • The purpose of the variety and keeping quality. This variety has a high taste, and also contains an increased amount of carotene. Best suited for fresh consumption, as well as for canning. Keeping quality indicators are at the level of 82-92%.
  • Growing regions. The variety is allowed for cultivation throughout Russia, with the exception of the Northern, North-Western and Ural regions.
  • Where it is recommended to grow. This type of carrot is recommended for outdoor cultivation.
  • Disease resistance. Variety NIIOH 336 does not very well withstand the most common diseases in carrots. Presowing seed preparation is an excellent prevention of many diseases, but it is not always enough.
  • Ripening period. The variety is mid-season, since the growing season from the moment the first shoots appear is 110-120 days. However, in regions with a warm climate, maturation occurs much faster - in 80-90 days. Learn about other ripening carrots.
  • What types of soil does he prefer. The variety prefers light, loose soils with low acidity.

Breeding history

The variety was obtained in 1978 at the All-Russian Research Institute of Vegetable Growing by crossing Vitamin and a hybrid of the 5th category.

Growing

  1. For carrots, it is important to choose open, well-lit areas. A few weeks before planting, it is recommended to add humus or compost (at the rate of 4 kg / m²) to the soil. Seeds should also be prepared in advance - soak in a weak solution of manganese or use the drug "Hom". Such treatment will disinfect the seeds, as well as increase their immunity against diseases.
  2. Sowing is best done on a sunny day. First, grooves are made in the soil up to 1-2 cm deep. The distance between the seeds is left about 0.5 cm, then the soil is leveled and watered abundantly.
  3. Further care consists in thinning - the first thinning should be done two weeks after sowing. The second thinning is about three weeks later. The distance between the plants is left at least 5 cm. If you do not thin out, the carrots will begin to deform due to lack of space or grow too small.
  4. The variety needs sufficient watering - depending on weather conditions, you need to water the root crops once every 4-7 days. It is recommended to water carrots between rows, and not under bushes.
  5. Carrots respond well to fertilizers, therefore, during the season, three additional feeding can be done:
    • During the period of intensive growth, you can use superphosphate (50 g per 10 l of water).
    • At the time of flowering, potassium nitrate is suitable (30 g per 10 liters of water).
    • During the fruiting period, you can add ammonium nitrate (30 g per 10 l of water).

Harvesting and storage

Like other varieties, NIIOH 336 must be harvested before the onset of frost. In addition to calculating the date for harvesting based on the ripening time of a given variety, you can also focus on the yellowing of the lower leaves.

As soon as the soil on the pulled root crops has dried, the tops should be removed.

Before storing, the carrots are sorted out and damaged or diseased roots are laid. To increase the keeping quality of the crop and protect it from diseases, you can dust the carrots with powdered chalk. The method of pouring carrots with pre-calcined wet sand or coniferous sawdust is also practiced.

Diseases and pests

This variety is distinguished by average immunity to most diseases, therefore, it is important not only to carry out preventive preparation of seeds for planting, but also to know how to fight diseases:

  • Treatment with Fofatox solution will help with late blight.
  • For root rot - colloidal salt solution.
  • For powdery mildew, the drug "Regent" is suitable.

Parasites can also often become a headache for gardeners growing this variety.

  1. To combat aphids, you can use the drug "Oxyhom".
  2. The drug "LyuksBor" will help against midges.
  3. A wood ash solution can be used against the Colorado potato beetle.
  4. From the bear - Bordeaux liquid.

Various problems in growing and ways to solve them

Failure to comply with the rules of agricultural technology, adverse weather conditions, poor-quality seed material and other factors can lead to certain problems when growing carrots.

Knowing the ways to solve these problems, with timely action, you can save the future harvest or avoid repeating the same mistakes and problems in the next season:

  • Seedlings or tops turn yellow, stretch and weaken - if the cause is parasites, then drugs "Aktara", "Ekogel", "Zircon" are used to combat them.

    In the case of a disease with phomosis (seedlings begin to turn yellow from below), brown spotting (seedlings first turn yellow from the edges, and then turn brown) or rhizoctonia, the plants will have to be destroyed, since during further storage they can infect the rest of the crop.

  • White core inside - the reason may be poor-quality seed material, as well as an excess of nitrogen against the background of a deficiency. In the second case, adjusting the fertilization scheme will help solve this problem.
  • Root vegetables are cracking - this is due to uneven watering, excess fertilizers, heavy soil, overripening of an early variety. It is important to monitor the uniformity of watering, to correctly apply fertilizers (especially to be careful with nitrogenous ones).

    If the site has heavy clay soil, it is worth giving preference to varieties with short root crops or planting carrots in bulk beds.

  • Carrots grow unsweetened and dry - these may be features of a particular variety, as well as a lack of watering or fertilization.
  • Deformed roots - the reasons for this phenomenon may be poor soil preparation (many stones), lack of watering in the first month after planting, improperly selected fertilizers (manure, potassium chloride and potassium salt cannot be used) and pest infestation.
  • Carrots grow very small - it can be features of a certain type, lack of sun or, on the contrary, excessive heat. In the latter case, it is worth increasing the amount of watering.

Perhaps the soil on the site is unsuitable - too heavy or with high acidity. To correct this situation in the next season will help the introduction of sand at the stage of preparing the soil for planting, as well as lime or dolomite flour.

Similar types of carrots

The closest in taste, ripening time, yield and keeping quality, as well as in appearance, are the following varieties of carrots:

  • Altair F1.
  • Losinoostrovskaya 13.
  • Incomparable.
  • Forto F1.

The NIIOH 336 variety is widespread due to its adaptability to cultivation in almost all regions of Russia. The lack of specific features of crop care, high yield and keeping quality of this variety make it attractive for growing in garden plots.

However, not very high immunity against most common diseases makes it necessary to prepare seeds for preventive maintenance before planting and further close monitoring of the condition of the plants.
